Analysis of Covariance

2021
ANCOVA of designed experiments combines one categorical and one continuous explanatory variable. Panel plots are usually the best way to graphically display ANCOVA designs, with a separate linear regression within each level of the factor. ANCOVA can test for effects of both variables and interactions between them.

Analysis of Variance and Covariance

1983
This chapter concerns linear models of the form $$ y = X\beta + e $$ with e ~ N(0, σ 2 Iwhere y and e are random vectors of length N, X is an N × p matrix of constants, s is a vector of p parameters and I is the unit matrix. These models differ from the regression models of the previous chapter in that X, called the design matrix, consists ...

Nonparametric Analysis of Covariance by Matching

Biometrics, 1982
The basic problem under consideration is the comparison of treatments with respect to a response Y when a covariable X is taken into account. Various methods involving matching may be regarded as compromises between the standard analysis of covariance and the standard analysis of independent matched pairs.

Adding additional covariates and the Analysis of Covariance

2010
Suppose that having fitted the regression model $$\vec{y} = X\beta + \epsilon, $$ (M0) we wish to introduce qadditional explanatory variables into our model. The augmented regression model, M A , say becomes $$\vec{y} = X\beta + Z\gamma + \epsilon.
